Architecture for Controlling your Theater
The architecture for controlling your theater will consist of a Domain
Controller with IR or serial cables connected to each component of your
theater.
In the example at the right, the Domain Controller is the small silver box
between the TV and the rest of the equipment. The remote control on the
left will use RF to send button press information to the Domain Controller.
Since it is RF, you do not have to point the remote control at the Domain
Controller and it will not be affected by plasma screen TVs. In addition,
the remote control only sends a very short burst of data indicating what
button was pressed - the Domain Controller does the rest.
The Domain Controller is connected to every AV component that needs to
be controlled (e.g., DVD player, cable or satellite receiver, TiVo, AV
surround processor, TV, etc), but not to the speakers or other components
that do not need to be controlled.
The easiest way to connect to the AV components is with an IR mouse
emitter (specifically, the Xantech 232M or 283M Mouse Emitter).
Alternatively, you can use RS-232 connections.
AV components that only have toggle on/off commands require an
additional connection. The Domain Controller always wants to know
whether an AV component is powered up or not. If the AV component has
discrete IR commands for power on and power off, the Domain Controller
can use these commands to know the state. However, if the AV
component only has a toggle power on/off command, then Power Status
must be determined by one of the methods below.
Add IR Emitters to your AV components.
Locate where to install IR emitters. To find out where the IR receiver is located on the AV component, use a sheet of cardboard
with a small hole in the middle of it. Place the cardboard against the front of the AV component and move the hole around the front
while sending IR commands to the AV component via the remote control that came with it. There should only be a small area
where the IR commands can be received. That area is the IR receiver. Paste the IR emitter on top of it.
Install IR emitters (or serial cables) to all your AV components. It is a good idea to label the Domain 3000 end of the wire with the
name of the AV component it is connected to and the port of the Domain 3000 that it is plugged into.
